1623E - A softer, water permeable Tyvek fabric, grade 1623E (Formerly 1622E) is also available, click here or see 'Recommended' tab below. This grade may be preferable where extra breathability is required, without the need for water resistance.

Please note: The manufacturer of Tyvek, Dupont, have changed the name of this material. All of our stock is suitable for archival storage and packaging - Tyvek® 1443R will become Tyvek® 1442R. In the interim, some stock may be labelled up with the old name.
